To all: whom it mag concern Be it known thatI, JOHNv SPENCE, of the;

city of Lethbridgaa in the Province of Al-v bert'a', Canada, haveinvented certain newand useful Improvements" in Grate-@pening- Devices,of which the following is the speci-f fication.

My invention relatesto a device for open-o ing gates, and the object ofthe invention is? and durable deviceof this class. a

With the above object in view the 1nven-1 tion consists essentially inthe arrangement and construction of parts hereinafter more! iparticularly described and later pointed: out in the appended claims. a1

Fig. 5 isan enlarged de-: tailed side view of the rollers carried by the topcross beam. Fig. 6 is al'sectional View; through the track secured toone of the fence boards. Fig- 7 is a sectional view; through the trackcarried by the spannen;

Inthe drawings like characters of refer-1 ence indicate correspondingparts in each figure. J a v 1 and 2 represent upright gate posts firmlyembedded in the ground 3 andrcon: nected at the top by a spanner 4. j

end of the spanner andhaving the ends thereof supported by braces(ija-nd 7 which pass angularly between thecrossbeam and the post 1. a

8' represents afence post whichis con:- nected to the gate post by theusual fence boards 9.

10 is a gateformed from inner and outer upright end beams 11 and 12-connectedby cross bars 13. The beam 12 is considerably longer than thebeam 11 and it is reinforced by an angularly disposed brace beam 14:,

15 is a track secured permanently to the upper of the fence boards 9,which track supports a roller 16 fastened to'the upper end of theupright beam 11. i

17 is. a track secured permanently to the spanner andsupporting a roller18 carried by a special casting 18 tothe upper end of the upright beam12. 'These rollers it will be seen support the gate so that it can beshifted backwardly and forwardly as desired. The casting '18 presents asheath for the' roller 1 8 and is supplied at, the inner side-with twoopposing lugs 18 and at the outer side with a single lug 18 19 is alocking bar pivotally secured by a pm 19 tothe lugs-18;, and having thefree end more or less in theform of a spear point presenting notches. 20and 21', The body. of

the locking. bar is. provided with an opening I i A 23 in whichi-s-located a roller 24'. to provide an lnexpenslve, easily operated I25 is a spring pressed latch pivotally faswardend designed to, passover. a pin 2-7; se-

, cured to; the post 21 A is a ring located directly under the ;lockingbar and; carried by two cables 28 and 29 which pass upgwardly throughthe open- ;i'ng 23 over the, roller 2 L around pulleys i 31 located onthe underside of the; top; beam loafter which they, are passed inopposite directions, outw-ar ;ly over further pulleys 32 located at. theend of the cross beam 5.

The endsof the cables are supplied with hand, grips 3,4 respecti'trely,while weights 35 are tied tothem between the pulleys 32 andthe handgrips A wire 13 connectsthe ring A with ;j the spring. latch QbfThe ringA is supgplied large enough so that it will not. pass throughth'eopening 23 in the locking bar and it is positioned sufficiently farbelow the locking bar to-a'llow the cables to release t the spring latch2 5gprior to, the ring. en 5' is a top beam secured centrally to onegaging with the locking bar; I

36 is a dividing plate appearingbetween the pulleys 31, 37 are shortcatch rods It will at this point be readily seen that if one pullson oneo -other of the cables 28 or 29 he willfirst lift the latch 25 torelease the gate and then he will swing the catch bar to one side" orother so the catch bar will lock the gate open as soon as it engageswith one or other of the catch rods 37.

38 is a cable or rope tied to the lug 18 and passing over a pulley 39carried by the post 3; The free endof said cable carries a weight 40sufliciently heavy to draw the gate closed when the catch bar isreleased.

The operation of the attachment is 'now described assuming a personapproaching the gate in a vehicle and that the gate is closed. At thetime the driver comes within range ofthe piece he grabs it and pulls,which action causes the gate to be opened, the pulled cable initiallyraising the latch and finally drawing the gate over so that the lockingbar engages with one of the catch pins. When this occurs the cable canbe released as the gate is locked open and the vehicle can then passthrough the gate opening. Upon reaching the opposite side bracket 41 tothe base of the post 1. Two

stops 42 are also fastened to each side'of the post 2 and receive theouter end of the gate when it is closed assisting the latch in holdingit firmly. What I claim as my invention is 1. The combination with agate and tracks 'suppor'ting'the gate, of weighted means holding thegate'normally closed, hand grips connected to the gate and located atthe approach to and beyond the same, and means for locking the gate inthe open position,

said; latter means being set in'the locking position by a pull on thehand grip on the approaching side of the gate and released from thelocking position by a pull on the hand grip located'beyond the gate, asand for thepurpose specified.

2. The combination with a gate, a track supporting one end of the gateand located at the end thereof, and an elevated track supporting theother end of the gate and located above the same, of weighted meansdesigned to continuously close the gate, re-
